on to discuss: Rememberr=ΣR,s=Σs, then σr+Σ(p-s) =r+μp-s, as had been said at the time of the proof of the Gaussian lemma,R1,R2,R3... ..rk,p-s1,p-s2,... p-sμ is,.., (p-1)/2of an arrangement, then(A ) * ((P-1)/2) * ((p-1)/2+1) = (P²-1)/8=r+μp-s, and then it's easy to pushr=s-μp+ (P²-1)/8. Next, consider all the formulas:Iq=[iq/p]p+ti (with remainder Division), if you put these formulas onISum,Q∑i=pΣ[iq/p]+∑ri+∑si, namelyQ (P²-1)/8=pΣ[Iq/p]+r+sand Willr=s-μp+ (P²-1)/8generation, you have

Many domestic counterparts in addition to Qualcomm pay royalties, not to any patent holders to pay royalties, such a market is very unfair, the Huawei Terminal is not fair. "Huawei Terminal Chairman Yu Chengdong recently accepted the south to continue the" big Mouth "nature," domestic terminal counterparts at least to set aside more than 10% of the sales revenue to pay for high-pass patent fees, but their net profit rarely can be 10%. " "means that on
update iteration speed will not be synchronized, ultimately leading to domestic consumers can not enjoy the same quality services.While the swap configuration is not fresh, with HTC One M9 plus for example, although the screen greatly upgraded, but the core of the processor is replaced by the Qualcomm Snapdragon Dragon 810 for MediaTek's flagship chip MT6795. Although both use four A57 cores and four A53 cores for the size of the core asynchronous ar
Because the previous laptop configuration was too low to meet scientific research requirements, I bought a fairly new computer. I have installed Ubuntu12.04 + WIN7 in a Linux environment. However, the problem is that my wired network card cannot be found under Ubuntu, and the network card under WIN7 is normal. Run the following command in Ubuntu to query the NIC model: lspci-k | grep-i-A2net: 02: 00.0 Ethernetc
